Mine is the same. Though it's also saying that my battery is at 99% charge after having it plugged in all night and booting it up. The capacity has been going up and down- currently at 5857mah of the designed capacity of 5770mah. It went from 5814 to 5788 in a day, and progressively back up to where it is now. My MBP is only a few weeks old if that means anything and I haven't properly "calibrated" the battery. I've drained it pretty low and then charged it back up a few times but that's it.
